Jack Clark, a PCA National Advisory Board Member and member of the U.S. Rugby Hall of Fame, has over 35 years coaching experience and is head coach for the University of California Varsity Rugby (@CalVarsityRugby) team, where he has won 27 combined national collegiate championships with an all-time collegiate coaching record of 614-78-5 (.880) in 15s and 109-14 (.886) in the Olympic Games version of 7s.

Clark strongly believes that focusing on the strengths of his players works exponentially better than focusing on their weaknesses. He says that the best way to pull his team out of a funk is to find something positive they are doing and focus on that. Find and highlight what skillsets his kids do have instead of criticizing the one's they do not. He says that in all his years, negativity has never worked for him, so coaches should always try to lean on the positive side.
